Call Through is always interesting when Call-by-call is not possible - for example, for consumers who are not customers of Deutsche Telekom. In Callthrough you dial a free 0800 number or a local landline numbers from our system. The account now checks whether enough credit and a valid price list is stored. If all checks succeed, the call is forwarded to your desired party and you can call super low worldwide.

Callback is an alternative solution to the call through method. With Callback customer calls whitch do not have a fixed-Flat. With Callback you call a free 0800 number or a local landline numbers from our system and hear a busy signal. Now, our system automatically calls you back and connects you to your desired participants abroad. In callback, should be noted however that both connections will be billed to your account. Once the connection to your landline or mobile phone and the connection to your desired participants abroad.
